Micro-optical Label Systems Analysis And Design

Ordinary barcode technology and RFID technology is now widely used in various occasions,as supplemental information recognition technology，2009，MIT proposed bokode micro-opticallabel technology.Bokode puts a micro miniature optical lens in front of barcode,then this system andreceiving optiacal system composed one system,so that the micro barcode can be received andidentificated by the receiving system. This technology has miniaturized,high-capacity and highsecurity,etc., but the receiving end can only use a large aperture telephoto lens can be morelong-distance reception and recognition.Paper re-analyzed this system,analyze the relationship between various parameters and theeffects to system of various parameters.Zemax is used to simulate this system and give theresult.We provide a theoretical basis to the current problem in this system. For the receiving endof the lens parameters required,we introduce a large aperture， long focal length lens called anannular aperture ultra-thin lens,this lens has large aperture，long focal lenth and ultra-thincharacteristics.we use Zemax to simulate this lens and composed to our transmitter,we got thesimulate result and proposed amendments to this system. Finally,paper discussed other applicationsof the annular aperture ultra-thin lens and the need for improvement.
